BiteWise

A local-first nutrition and training diary for Indian home cooking.

Status: Active
Date: October 2026
Category: Applications

Summary

A React Native diary built around Indian home food rather than barcodes and restaurant portions: 174 foods in SI units, twelve micronutrients against ICMR-NIN 2020 reference intakes, and optional AI that only runs on a key the user supplies.

Description

BiteWise is a nutrition and training diary built for people who cook, rather than barcodes and restaurant portions. Its catalogue ships 105 Indian dishes as first-class rows measured in grams, each carrying micronutrients, and any value can be corrected in place to match how a household cooks. The diary lives entirely on the device in AsyncStorage and works offline, and the app never invents a number: missing micronutrients are unknown, and AI only identifies a catalogue row while every calorie and macro is computed locally. It ships as a downloadable Android build with 121 behavioural checks.

Features

Indian-first catalogue in SI units: 174 foods, 105 dishes, with per-user overrides for any value.
Four ways to log: catalogue search, sentence parsing, barcode lookup and manual FSSAI entry.
Insights that show their working: nutrient gaps and consistency trends with days examined.
Optional AI, constrained: AI identifies a catalogue row and the app computes every number.
Local-first privacy: no analytics, no account; the diary works offline and stays on the device.
